Sparkplugs for '76 Johnson

[Rattle-]

I have a 9.9 Seahorse and changing the plugs for the first time. I bought it last year. Found on-line the Champion UL81J fits this motor.<br />However the plugs that are in it, are L82C Champion. It has ran beautifully this last year, so what should I replace them with? The motor is mostly trolling.<br />Thanks for any help...<br />Kerry
